Important Notes Table 5: Fabric OS Area Information (Continued) Fabric OS Area Single domain WWN card FRU repair Zoning: license Zoning: domain ID Description The SAN Director 2/128 can be configured only as a single domain, as opposed to two logical domains in the Core Switch 2/64. In other words, all port blades and slots are a part of that single switch. If an HA failover or power cycle occurs during a FRU replacement on the WWN card, the SAN Director 2/128 becomes nonoperational. CAUTION: When performing a FRU replacement on a WWN card, complete the FRU procedure before attempting an HA failover or power cycling the chassis. To use zoning in a non-RCS (reliable commit service) mode fabric (that is, in a fabric containing switches with firmware versions other than v2.6.x, v3.1, and v4.1), HP recommends that all appropriate zoning licenses be installed on all the switches in the fabric before attempting to bring a switch in to the fabric. If the zoning license is to be removed, the user must make sure it is reinstalled properly on the affected switch before attempting the cfgenable zoning operation. Failure to follow these steps can cause inconsistency of zoning configuration on the affected switches if a zoning operation is attempted from a remote switch in the fabric. On the affected switches, an error message appears on the console or Telnet session (or by issuing the errShow or errDump command), indicating that the zoning license is missing. Domain 0 in a zoning configuration file is invalid but was not previously enforced. Workaround: Prior to upgrading a switch to Fabric OS v4.2.x, ensure that the fabric's zoning configuration does not contain domain ID 0, which is used for zoning. This is specific only to 4.x switches. SAN Director 2/128 Fabric OS 4.2.x Release Notes 19
